SLIDING GLASS WINDOW. e

Application filed December 29, 1921.

T 0 all whom it may concern:

Be it known that we, ROBERT MARTIN CHAMBERS and JosnPH JACKSON, both British subjects, and both resident at 106 University Street, Belfast, Ireland, have invented certain new and useful Improvements in Sliding Glass Windows, of which the following is a specification.

This invention has reference to improvements in Or relating to sliding windows, more particularly carriage windows of the franieless-glass type, and it consists mainly in the combination with a window which is slidable vertically in fixed guideways in which the lateral margins of the glass fit closely, of a water-plate or weather-plate which is hingedly mounted on the window sill and bears normally against the outer face of the glass and is adapted to engage the window automatically when it has been raised into its highest or closed position and to support it securely in that position. The invention also comprises the combination with this water plate of means for effectively supporting the window at a number of intermediate positions between the fully open and fully closed positions.

The grooves in the stiles in which sliding windows of the kind in question are mounted are usually tapering grooves, and thewater plate is usually a fixed plate attached to the sill, a channel of metal being usually fixed to the bottom of the glass and a lip being formed on or attached to this channel throughout its length and extending outwards and downwards, so that after raising the window and pushing it outwards the lip engages over the fixed water plate. A variation of this arrangement is also known in which the window slides in channels which are free to swing or move outwards in their fittings to allow the lip to engage over the water plate. This freedom of movement of the window causes body noises in the carriage, due to loose fitting and to vibration of the carriage, and it is one of the objects of our invention to obviate all rattling of the window.

We have illustrated an embodiment of our invention in the accompanying drawing, in which Fig. 1 is aside elevation, partly in section, of a carriage door fitted with a vertically slidable fra meless glass window and provided with a hinged water plate and means for supporting the glass in various Serial No. 525,548.

positions in accordance with our invention;

and v Fig. 2 is an elevation on a smaller scale of the same door with its inner panel re moved and the glass supported in a position intermediate between the fully open and fully closed positions of the window.

Referring to the drawing, A is a water or weather plate hinged at a on the outside edge of the window sill. The free longitudinal margin 6 of this plate is bent upwards to adapt it to engage, when the window is closed, in the horizontal groove formed behind the lip c of a metal channel 03 which is fixed to the bottom edge of the glass 6. The inner face of the upturned margin 6, which may be faced with rubber or a strip of felt, bears normally against the outer face of the glass when the glass is being lowered or is supported in an intermediate position, so that the plate A sheds ofi rain water running down the face of the glass not only when the window is closed but also when it is partially open. The lateral margins of the glass 6 fit slidably in parallel grooves formed in the side members of the door frame, or in channels 0' firmly fixed thereto.

B is a bar which is pivotally connected to the water plate A at f and to a link C at g so that it hangs in a plane parallel to the face of the glass and, when the water plate is swung on its hinge, has a parallel motion towards or away from the glass imparted to it. The water plate is raised by means of a handle it the stem of which is rigidly connected to the said plate and extends inside the carriage through a slot formed in the frame at one side of the window, and the window is raised and lowered by means of a knob 2' which is attached to the upper part of the glass. The bar B is formed or provided with a series of projections, j, for supporting the glass at various heights, the said projections being adapted for example to engage the lip 0 like the margin 6 of the water plate. These projections are shown as lugs stamped out of the bar B, but they may be in the form of hooks or pawls mounted on the said bar.

In closing the window it is unnecessary to operate the handle h, the lip c of the channel (Z riding over the successive lugs y' as the glass is raised and causing the water plate to swing upwards on its hinge when it contacts with the upturned margin 6 of the said plate. As soon as the lip c is clear of the S id margin Z) the water plate swings back To open the window, the glass is raised slightly to permit of the handle it being operated to cause the water plate to swing upwards and outwards. The glass can then be lowered, to the desired extent, the handle being released as soon as the lip c has passed below the waten plate if the glass is to be supported upon the uppermost lug j. On releasing the handle the lug or pawl next belowthe bottom edge of the window engages the channel lip automatically and the weight of the glass acts to keep the water plate in close contact with the outer face of the glass.

Instead of a single bar, such as B, apair of depending bars, each similarly providedwith lugs, hooks or pawls,,maybe employed; and, other details ofconstruotion, such as the adaptationof the water plate to engage the window and the means for supporting the window in intermediate positions, may be 'varied.

hat we claim is 1', The combination with a window casing, of an unframed} glass panel slidable verticallyin fined guidewaysin said window casing, in; which the-lateral, margins of the glass fit closely, whereby thepanel has no move mentin a direction transversely thereof, a weather-plate pivotally mounted on the window sill on the exterior of the panel, and adapted to bear against the glass as the panel is raised orlowered, said panel having a lip on its exterior and above its lower edge, which lip is adapted to engage said weather-plate when the panel is fully raised, whereby the weather-plate operates to sup port the panel. in raised position.

2. The combination with a window in the form of an unframed glass panel which is slidable vertically in fixed guideways, of a weather-plate pivoted to the window sill on the exterior of the window and adapted to bear against the outer face of the glass as the window is raised and lowered, said window having means associated therewith to engage the weather-plate when the window is fully raised whereby said weather-plate supports. the window in raised position, and means connected to the weather-plate and situated beneath the latter for supporting the window in: intermediate positions between fully open and fully closed positions.

3. The combination with a window in the form of: an unframed: glass panel which is slidable vertically in fixed: guideways, of a weather-plate pii'voted to the exterior of the window sill and adapted to rest againstrthe outer face of the glass as the window is raised or lowered, means associated with the window to engage the weather-plate when the window is fully. raised whereby the weather-plate may support the window, and means'accessible on the inside of the window for operating said weather-plate.

l. The combination with a window in the form of an unframed glass panel which; is slidable vertically in fixed guideways and is opened by a downward sliding movement, of a weathen-plate pivoted to the exterior of the window sill and adaptedto rest against the outen face of the; glass as the window is raised? on lowered, means associated, with the window to engage the weather-plate; when the window is fully raised whereby the weather-plate may support the window, a handle connected tothe weather-plate for operatii'ig the latter and accessible on the inside ofthe window, and a bar pivotally, connected. to the weather-plate and depending therefrom, said bar having a plurality of projections to support the window in intermediate positions.

In testimony whereof we have aflixed our signatures,
